I'm using Premiere CS6 for a while now, but until today I had a non Nvidia GPU and therefore could not make use of the Mercury playback engine and GPU acceleration.
After reading online about the advantages it gives, I decided to sell my ATI card and bought a Nvidia GTX 660 today.
After enabling the card and 'unlocking' the MPE and GPU acceleration and changing to 'maximum render quality' enabled as advised by this post over here 'http://www.studio1productions.com/Articles/PremiereCS5-2.htm', I gave it a go.
Ok, it's very nice that I now don't get a red bar when I apply GPU accelerated effects such as color correction, motions and cross dissolves and can playback the video in realtime without having to render first.
But also, I read before that the render and export times would be greatly improved. Sometimes even 10 times faster. Without testing it vigorously, that isn't the case here. I would say its about 30% faster.
I checked the GPU activity during rendering / exporting, as well as during playback of the effects, and never had my GPU more activity than 50%. Sometimes it was doing only 10%.
Does that mean my GPU is bottlenecked by the rest of my system? Did I have unrealistic expectations? And what are the improvements I actually could expect?
System information:
CPU: i5 2500k
GPU: GTX 660
RAM: 8GB @ 1333 mhz
HDD: 1TB @ 7200 rpm
OS: Windows 7 64-bit
I edit GH3 / 5D files so that would be h.264 compressed files.
Thanks for sharing your knowledge.
Edit:
Just found out that an effect that I often use was not GPU accelerated and this hold the process down I guess. Just did a timeline render with only GPU accelerated effects applied and it took 7 minutes, whereas before this would be probably around 30 minutes. So huge increase there. The GPU was working at 50-60% so that's also better. Still would like to know how much gains would be to be expected.
